This Tomei 2020-2021 Toyota Supra GR Expreme Ti Full Titanium Muffler Kit Type-D Dual Exit Exhaust is lightweight, strong, and durable. Tomei sources their own raw materials, allowing them to significantly improve quality while also keeping the price low. In addition to that, having complete control over the raw materials and manufacturing process allows Tomei to produce high-quality products at an affordable price.
The main pipe in the Type-D exhaust is 3.17in and the tips are 4.53 versus the stock main pipe being at 3.17in and 3.90in for the tips
Not only is the stock main pipe covered with unnecessary dents, resulting in poor exhaust flow. The exhaust pipe also differs in diameter, which restricts the exhaust flow. And the stock exhaust weighs significantly more than the Type-D. 25.1kg vs 11.0kg.
The 152 silencer casing with 1mm wall thickness is made with exhaust efficiency in mind. Each unity is embossed with Tomeiâ€™s signature logo, then polished, then heat-treated for that signature look.
The all-titanium 1mm thick inner tube features 3 perforations spaced 5mm apart to achieve an open area ratio of 32.6%. Using titanium maximizes weight reduction and durability while also providing that distinct racing sound.
Long fiberglass wool is used in all Tomei silencers. Compared to short fiberglass wool, longer fibers are much more resilient to wear especially against prolonged high temperature/pressure conditions.
This kit includes all the components necessary for installation including the bolts and nuts. Bolt Smooth Paste is also included to help prevent the bolts from becoming seized under heat.
